The fragrance-containing sheet for smoking articles according to one ormore embodiments of the present disclosure may be included within thefirst portion 110 and 210, or the second portion 120 and 220 of thesmoking article 100 and 200 shown in FIGS. 1 and 2.

In order to prepare the fragrance-containing sheet for smoking articlesaccording to one or more embodiments of the present disclosure, a slurry(or crude liquid) including distilled water, alcohol, modified celluloseand fragrance may be used. The slurry may further contain at least oneof a bulking agent, an aerosol former, and an emulsifier.

The slurry may include about 1 wt % to about 80 wt % of alcohol. Assuch, the modified cellulose may be better dissolved.

More specifically, distilled water and alcohol may be mixed in a weightratio of about 1:1 to about 10:1 in the slurry. Preferably, distilledwater and alcohol may be mixed in a weight ratio of about 2.33:1. Assuch, the modified cellulose may be better dissolved.

Distilled water may be a factor that determines viscosity of the slurry.

Alcohol may be utilized as a solvent. The alcohol may be, for example,ethanol. When ethanol is included in the slurry, modified cellulose suchas HPMC, methyl cellulose (MC), carboxymethyl cellulose (CMC), or ethylcellulose (EC), and fragrance components such as L-menthol may be welldissolved in the slurry at room temperature.

The modified cellulose may be cellulose in which a specific functionalgroup is substituted in a molecular structure. The modified cellulosemay be, for example, hydroxypropyl methyl cellulose (HPMC), methylcellulose (MC), carboxymethyl cellulose (CMC), or ethyl cellulose (EC).Hydroxypropyl methyl cellulose may have a grade within a range of about4 to about 40000 depending on a degree of substitution by ahydroxypropyl group and a methyl group (or methoxy group). Viscosity ofhydroxypropyl methyl cellulose may be determined depending on a grade.

The modified cellulose may be, for example, AN6, AN15, AN50, BN10, BN50,MC15, or MC50, which are product names of Lotte Fine Chemicals.

In experiments where MC15 or MC50 (cellulose with a methyl groupsubstituent) are used as the modified cellulose, viscositycharacteristics, slurry formation characteristics, dryingcharacteristics, sheet physical properties, and fragrance retentionproperties of the fragrance-containing sheet have been confirmed to beexcellent. In that case, the fragrance-containing sheet for smokingarticles may have a viscosity in a range of about 100 cp to about 10,000cp when preparing the slurry.

The fragrance may include, for example, menthol, leaf tobacco extracts,natural botanical fragrance (e.g., cinnamon, sage, herbs, chamomile,reeds, persimmon tea, cloves, lavender, cardamom, cloves, nutmeg,bergamot, geranium, honey essence, rose oil, lemon, orange, cinnamon,caraway, jasmine, ginger, coriander, vanilla extract, spearmint,peppermint, cassia, coffee, celery, cascarilla, sandalwood, cocoa,ylang-ylang, fennel, anise, licorice, St. John's bread, plum extract,peach extract, etc.), sugars (e.g., glucose, fructose, isomer sugar,caramel, etc.), cocoa (powder, extract, etc.), esters (e.g., isoamylacetate, linalyl acetate, isoamyl propionate, linalyl butyrate, etc.),ketones (e.g., menthone, ionone, damasenone, ethyl maltol, etc.),alcohol classes (e.g., geraniol, linalol, anetol, eugenol, etc.),aldehydes (e.g., vanillin, benzaldehyde, anisaldehyde, etc.), lactones(e.g., γ-undecalactone), γ-nonalactone, etc.), animal flavors (e.g.,musk, amber lys, civet, castrium, etc.), hydrocarbons (e.g., limonene,pinene, etc.).

The fragrance may be used in a solid state, or may be dissolved ordispersed in an appropriate solvent such as propylene glycol, ethylalcohol, benzyl alcohol, or triethyl citrate. In addition, fragrancesthat are easily dispersed in a solvent by the addition of an emulsifier,for example, hydrophobic fragrances, oil soluble fragrances, and thelike may be used. These fragrances may be used alone or as a mixture.However, embodiments of the present disclosure are not necessarilylimited thereto, and embodiments of the present disclosure may includeany fragrances used in the smoking article.

The bulking agent serves to increase a total mass (i.e., dry mattermass) of constituents other than the water in the raw material slurry,thereby increasing a volume of the fragrance-containing sheet to beproduced. The bulking agent only serves to increase the volume of thefragrance-containing sheet and does not affect an original function ofthe fragrance-containing sheet. More specifically, the bulking agentdoes not substantially increase the viscosity of the raw materialslurry, and does not adversely affect a fragrance retention function ofthe fragrance-containing sheet.

The bulking agent may be starch or starch hydrolyzate. The starchhydrolyzate refers to a substance obtained by a process of hydrolyzingstarch. The starch hydrolyzate is, for example, a substance obtained bydirectly hydrolyzing starch (i.e., dextrin), or a substance obtained byhydrolyzing starch after heat treatment (i.e., indigestible dextrin).The bulking agent may be, for example, dextrin, and more specifically,cyclodextrin.

The starch hydrolyzate may, generally, be a starch hydrolyzate having adextrose equivalent (DE) value within a range of about 2 to about 40,and preferably a starch hydrolyzate having a DE value within a range ofabout 2 to about 20. As a starch hydrolyzate having a DE value within arange of about 2 to about 20, for example, Finedex #100 (MatsutaniChemical Industries Co., Ltd.), Fine Fiber (Matsutani ChemicalIndustries Co., Ltd.), or TK-16 (Matsutani Chemical Industry Co., Ltd.)may be used.

The DE value may represent a degree of hydrolysis of starch, that is, asaccharification rate of starch. The DE value may be measured by aWillstatter-Schudel method. The DE value is measured, as a specificvalue, by the Willstatter-Schudel method. Properties of the hydrolyzedstarch (i.e., starch hydrolyzate), such as a molecular weight of thestarch hydrolyzate or an arrangement of sugar molecules constituting thestarch hydrolyzate, are not identical among the molecules of the starchhydrolyzate, and may differ according to a certain distribution orvariations. The starch hydrolyzate exhibits different physicalproperties (for example, DE value) for each molecule due to thedistribution and variations of the properties of the starch hydrolyzate,a difference in the cut section, or the like. As described above, thestarch hydrolyzate is a set of molecules representing different physicalproperties, but a result (i.e., DE value) measured by theWillstatter-Schudel method is regarded as a representative valueindicating a degree of hydrolysis of starch.

Preferably, the starch hydrolyzate may be selected from the groupconsisting of dextrin having a DE value of about 2 to about 5,indigestible dextrin having a DE value of about 10 to about 15, and amixture thereof. As dextrin having a DE value of about 2 to about 5, forexample, Finedex #100 (Masutani Chemical Industries Co., Ltd.) may beused. As indigestible dextrin having a DE value of about 10 to about 15,for example, fine fiber (Matsutani Chemical Co., Ltd.) may be used.

The fragrance-containing sheet may contain, based on a total of 100parts by weight, about 2 parts to about 15 parts by weight of moisture,about 25 parts to about 90 parts by weight of modified cellulose, andabout 0.1 parts to about 60 parts by weight of fragrance.

The slurry may further contain at least one of a bulking agent, anaerosol former, and an emulsifier. As described above, the bulking agentmay be, for example, dextrin, the aerosol former may be, for example, atleast one of glycerin and propylene glycol, and the emulsifier may be,for example, lecithin.

FIG. 3A is a diagram illustrating a fragrance-containing sheet 300before being dried, and FIG. 3B is a diagram illustrating afragrance-containing sheet 400 after being dried.

Referring to FIGS. 3A and 3B, the fragrance-containing sheet 300 beforebeing dried may have a thickness d1. The fragrance-containing sheet 400after being dried may have a thickness d2. The thickness d1 of thefragrance-containing sheet 300 before being dried may be greater thanthe thickness d2 of the fragrance-containing sheet 400 after beingdried. As an example, the fragrance-containing sheet 300 before beingdried may have a thickness of about 0.2 mm to about 2.0 mm, and thefragrance-containing sheet 400 after being dried may have a thickness ofabout 0.01 mm to about 0.3 mm. The above-described difference inthickness may be derived from a difference in moisture content due todrying.

FIG. 4 is diagram illustrating a cross-section of a first portion 500 ofa smoking article, according to an embodiment.

For example, FIG. 4 may be a cross-sectional view of the first portionof the smoking article of FIG. 1.

Referring to FIG. 4, the first portion 500 may include a tobaccomaterial 511 and a fragrance-containing sheet 513. The tobacco material511 may be, for example, in the form of a tobacco sheet such as leaftobacco cut fillers. Alternatively, the tobacco material 511 may be atobacco sheet impregnated with an aerosol generating material or thelike.

When the first portion 500 is combusted or heated, an aerosol may begenerated from the tobacco material 511, and a fragrance componentvolatilized from the fragrance-containing sheet 513 may move along withthe aerosol.

Hereinafter, advantages in the manufacture of the fragrance-containingsheet for smoking articles will be described in detail.

In general, when a slurry is prepared using a polysaccharide materialsuch as agar, gelatin, gellan gum, etc., the manufacturing process mayinclude the following operations: (1) heating water to about 80° C. toabout 100° C.; (2) adding and dissolving agar, gelatin, or gellan gum;(3) cooling down to about 60° C.; and (4) adding a fragrance componentsuch as menthol and the like.

In operation (3) above, the slurry is required to be maintained at about60° C. in a storage tank, a transfer line, an application nozzle, andthe like.

In addition, since fragrance components such as menthol are not solublein water, there is a need to use an emulsifier.

According to one or more embodiments of the present disclosure, theslurry of the fragrance-containing sheet for smoking articles mayinclude modified cellulose (e.g., HPMC, MC, CMC, or EC) having a gradewithin a specific numerical range. In addition, the slurry of thefragrance-containing sheet for smoking articles may contain, forexample, distilled water, ethanol, dextrin, glycerin, and menthol. Inthat case, dextrin and glycerin may be dissolved in distilled water atroom temperature, and the menthol and modified cellulose (e.g., HPMC,MC, CMC, or EC) may be dissolved in ethanol at room temperature.

The slurry of the fragrance-containing sheet for smoking articlesaccording to one or more embodiments of the present disclosure includesa relatively small amount of distilled water and at least a certainamount of alcohol. As such, there is an advantage in that drying time isrelatively short.

When preparing the slurry of the fragrance-containing sheet for smokingarticles according to one or more embodiments of the present disclosure,the manufacturing process may include the following operations: (1)dissolving menthol in ethanol, and adding and dispersing modifiedcellulose (e.g., HPMC, MC, CMC, or EC); (2) adding distilled water; and(3) adding a fragrance component. As such, a process of separatelyheating the slurry is not required, and accordingly there is no need tomaintain the temperature in the storage tank, the transfer line, theapplication nozzle, and the like. In addition, the slurry need notnecessarily contain an emulsifier.

Table 1 below shows a content proportion of each component of thefragrance-containing sheet for smoking articles according to anembodiment. Ethanol was all evaporated while the slurry was dried.
